2. To stop a car, the brakes on each wheel must dissipate a lot of energy in a short time. The disc brake rotor can get hot, about 1100° F (850 K). A rotor has an inner radius of 0.11m and an outer radius of 0.38m . Find the power dissipated by the four brake rotors through radiation (glowing) in both Watts and Horse Power. FAR Rotor (Each rotor has TWO sides)
